Feeding system for image forming machine

Abstract

There is provided a feeding system for an image forming machine using a first feeder roll and a press roll that form a nip between them though which a substrate is passed, and a second feeder roll located after a printing zone, where the first and second feeder roll surfaces move at the same speed.

1 . A feeding system for an image forming machine comprising a first feeder roll and a press roll having surfaces that form a nip between them though which a substrate is passed, and a second feeder roll having a surface and located after a printing zone, wherein said substrate passes from the first feeder roll, through the printing zone and to the second feeder roll, and wherein said first and second feeder roll surfaces move at the same speed.  
   
   
       2 . The feeding system of  claim 1  wherein said first and second feeder roll surfaces move at the same speed because they are driven by a common motor and are connected by driving belts or a gear system.  
   
   
       3 . The feeding system of  claim 1  wherein said rolls are made from butadiene acrylonitrile.  
   
   
       4 . The feeding system of  claim 1  further comprising a third feeder roll having a surface to which the substrate passes after said second feeder roll.  
   
   
       5 . The feeding system of  claim 4  wherein the surface of said third feeder roll surface moves at the same speed as said first and second feeder rolls.  
   
   
       6 . The feeding system of  claim 1  wherein said first and second feeder roll surfaces move at a speed between 1 and 30 meters per hour.  
   
   
       7 . The feeding system of  claim 6  wherein said first and second feeder roll surfaces move at a speed between 5 and 20 meters per hour.
